Beschreibung
Zusammenfassung:	Process for obtaining aqueous hydrogen peroxide solutions by the alkylanthraquinone process, providing a concentrated aqueous hydrogen peroxide solution with a low content of impurities, according to which a continuous addition of acidifying compounds and/or of stabilising compounds is performed, consisting in recycling towards the oxidation unit at least a part of the purge leaving the distillation unit.
